StumbleUpon’s Paid Discovery is a great way to get some exposure for your website or blog.

However, it can be difficult to find a full list of categories and interests to target.

Here we present an updated, unofficial, searchable text list of all StumbleUpon categories and interests.

When you’re creating a new campaign in Paid Discovery, you’ll get various options to target different groups of Stumbleupon users, such as age, gender, location and device. Finally, you can also choose interest bundles, or specific interests.

If you have a certain target audience for your content in mind, or if it’s very specific to certain groups, then you’ll want to manually select the interest areas at this stage, instead of using one of the broader bundles.

However, there are approx. 512 interest areas in StumbleUpon, and they’re not visible all at once, so it’s difficult to get an overview in order to select the best ones.

We’ve taken an unofficial snapshot (as of March 2014) of all of the interest areas available, and expanded them out into the ordered table of text below, so you can easily see what’s available.

Enjoy!

Note: The category headings and sub-headings are in bold and orange. The top-level category list is similar, but not exactly equivalent to the StumbleDNA colour coding seen elsewhere on user profiles.
